Toy Like Me accessories!

Epoxy I think works fairly well to sculpt onto the dolls but you'd have to then colour match the stump part. I really want a prosthetic leg as well because it would save me the hassle of having to cut a leg in half, sculpt a stump/socket part and then craft some sort of prosthesis out of metal rods and so on.
I don't think I really have the appropriate tools here.
